PAPER BOTTLE.

Specification of Letters Patent.

Application filed January 25, 1915. Serial No. 4,099.

To all whom it may concern:

Be it known that I, HARRY C. AYERsT, a citizen of the United States,residing at Seattle, in the county of King and State of Washington, haveinvented certain new and useful Improvements in Paper Bottles, of whichthe following is a specification.

This invention'relates to bottles which are molded from pulp formed ofpaper stock or an equivalent, by means of a suitable machine like, forexample, that illustrated and described in patent application, SerialNo. 869,243, filed by me October 29, 1914.

The object of the present invention is the production of a bottle formedof a pulpy material and which is designed, more especially, for use asmilk containers.

The invention consists of a novel construction of bottle, as will behereinafter described and claimed In the accompanying drawings, Figure 1is a transverse vertical section of" a bottle embodying my invention.Fig. 2 is a fragmentary front elevational view of the bottle shown inFig. 1. Fig. 3 is a longitudinal view of the preferred form of abottle-tap whereby the cream may be drawn from a bottle containing milk.

According to this invention, a bottle is formed of pressed or moldedwood' pulp or other suitable macerated material.

As illustrated in Fig. 1, A represents the body of the bottle having aneck B and an annular rabbet C in itsmouth to accommodate a capsuch;"for instance, asusuallyemployed for milk-bottle closures. Thebottle Wall is furthermore made at predetermined distances from its topwith relatively thin portions which are adapted to be removed by theinsertion of a tap for the purpose of withdrawing the cream from thebottles contents. Such weakened wallportions are formed by the provisionof recesses D and D inthe outer periphery of the wall and are desirablyeach formed with a flaring periphery E which terminates in an annulargroove F.

The referred to tap, see Fig. 3, comprises a tube G which tapers, as atH, toward the front end of the tap. The latter is made or sharpened topresent circular cutting edge .I and one or more serrations, as K, arecut into the tube to provide supplemental cutting edges L.

The tap is used by pushing the same into a selected one of the recessesD while imparting a rotary motion to the tap so that the wall materialis cut away at the bottom of the groove F to allow the tap to beinsertedin the bottle, as indicated by broken lines Gr in Fig. 1.

By reason of the taper on the tap, the latter, when shovedinto thebottle, tends to cause the surrounding portion of the bottle to embracethe tap and obviate any leakage thereat. a

The recesses D and D are positioned at different elevations, so thateither may be selected according to the desired quantity and quality ofthe cream.

The invention is of simple and inexpensive construction, and is designedto be destroyed after it has been once used.

What I claim-as my invention, is

As a new article of manufacture, a milk bottle made of molded pulphaving adjacent its upper end an integral weakened draw-off tapreceiving portion whereby substantially purer cream may be withdrawnfrom the bottle, and having between the aforesaid weakened portion andthe bottom of the bottle a second .weakened tap receiving portionwhereby a mixture of cream and milk may be withdrawn.
